|
|
|
48 Ediff provides a choice of two functions: ediff-setup-windows-plain, for
|
|
|
49 doing everything in one frame, and ediff-setup-windows-multiframe,
|
|
|
50 which sets the control panel in a separate frame. Also, if the latter
|
|
|
51 function detects that one of the buffers A/B is seen in some other frame,
|
|
|
52 it will try to keep that buffer in that frame.
|
|
|
53
|
|
|
54 If you don't like the two functions provided---write your own one.
|
|
|
55 The basic guidelines:
|
|
|
56 1. It should leave the control buffer current and the control window
|
|
|
57 selected.
|
|
|
58 2. It should set ediff-window-A, ediff-window-B, ediff-window-C,
|
|
|
59 and ediff-control-window to contain window objects that display
|
|
|
60 the corresponding buffers.
|
|
|
61 3. It should accept the following arguments:
|
|
|
62 buffer-A, buffer-B, buffer-C, control-buffer
|
|
|
63 Buffer C may not be used in jobs that compare only two buffers.
|
|
|
64 If you plan to do something fancy, take a close look at how the two
|
|

65 provided functions are written.")
